I did not get this message before updating my Dell monitor driver and color profile.* Return the PC to the previous condition either by loading a different ICM and driver or doing an operating system restore

Is there such a thing as Dell monitor calibration software?* No.

If not, what is the workaround for this?* None.

Would someone from Dell like to take ownership of this issue?* No. Engineering has already stated that they are not going to tweak every Dell monitor ICM for this Photshop software coding flaw. (As they stated)

Unfortunately, I am getting the same issue, I would like to fix this problem in anyway possible (if there are steps to do it). If I was informed about the issue with Photoshop and this monitor I wouldn't have purchased it, but to late to go back. Please inform me of a way to as you stated in the first answer, "Return the PC to the previous condition either by loading a different ICM and driver". Thank You.
